ios - How to perform a segue view from custom UITableViewCell(xib) to another ViewController -


i want show button on custom uitableviewcell takes user screen on tapping on it. have tried following code doesn't work

child view: 

@ibaction func childscreenbutton(sender: anyobject) {     if let delegate = self.delegate {         delegate.childbuttonclickedoncell(self)        }     }

protocol:

protocol childtablecelldelegate: class { func childbuttonclickedoncell(cell: childviewcell) }

parent viewcontroller: 

func childbuttonclickedoncell(cell: feedchildviewcell) {      self.clickedindexpath = self.feedstableview.indexpathforcell(cell)      self.performseguewithidentifier("tonextscreen", sender: self)  }

while i'm testing break point doesn't enter "delegate.childbuttonclickedoncell(self)" on child view. please let me know if doing wrong here. thanks!!

i suspect you've got couple things out of place, or not defined right.

i ran quick test this, , delegate call works fine... see if notice not-quite-the-same...
